(Thraupidae; Ϯ Green Warbler-finch C.olivacea) Dim. < genus Certhia Linnaeus, 1758, treecreeper; “CERTHIDEA (subgenus).   CERTHIDEA differt a genere Geospiza rostro graciliore et acutiore; naribus basalibus et non tectis; mandibulæ superioris margine recto; tarsis longioribus et gracilioribus.   CERTHIDEA OLIVACEA.  ...  Of the groups here characterized, Geospiza, Camarhynchus, and Cactornis, belong to one type; but with regard to Certhidea, Mr. Gould remarked that although he confidently believed that it should also be referred to the same group as the three former, yet in its slighter form and weaker bill it has so much the appearance of a member of the Sylviadae, that he would by no means insist upon the above view being adopted until the matter shall have been more fully investigated.” (Gould 1837) (see Geospiza).
Var. Certhidia.
